The nurse locates the pulmonic area at the second intercostal space, on the left side at the mid-clavicular line. This location is useful for assessing the pulmonic valve. The costovertebral angle is at the inferior aspect of the sternum. The costochondral junction is the point where a bony rib meets the cartilage connecting the rib to the sternum. The third intercostal space, Erb's point, is a useless location for cardiac or respiratory assessments.
